this is what i expect lol https://www.instructables.com/id/knex_knife_2/ and why does this spaz keep typing KNIFE –noun 1. an instrument for cutting , consisting essentially of a thin, sharp -edged, metal blade fitted with a handle. lol oh yea make this its way better

i like the simplicity, and the way the knife slides in and out of its holder. As for the knife itself, though, its not that great. I like the use of the blue panels in the blade, but you could easily of made the handle comfier and more sturdy, possibly by making it 3 connectors wide, rather than just a single, wimpy panel.
In short, a decent idea but needs a lot of work.
